bility of pricing changes in the transport sector : how to reconcile efficiency and equity ? – This paper elaborates an analytical framework of the acceptability of pricing changes in the transport sector. This framework is built on the confrontation of the economic efficiency, territorial equity, horizontal equity, and vertical equity dimensions. This analytical framework is then applied to some ongoing urban and suburban road toll schemes in various countries. The analysis shows that these efficiency and equity dimensions combine themselves, by most often reinforcing the ones the others in their negative or positive aspects. This analysis also shows that these various dimensions of equity cannot be ignored on pain of failure. It enables us to identify the ways according to which the acceptability of urban road pricing could be improved. Un cadre d'analyse de l'acceptabilité des changements tarifaires dans le secteur des transports est élaboré. Ce cadre analytique est bâti sur la confrontation des dimensions de l'efficacité économique, de l'équité territoriale, de l'équité horizontale et de l'équité verticale. Ce cadre analytique est appliqué à quelques expériences de péages routiers urbains ou suburbains dans divers pays. Leur analyse montre que les dimensions de l'efficacité et de l'équité se conjuguent, en se renforçant le plus souvent les unes les autres dans leurs aspects négatifs ou positifs. Cette analyse montre aussi que ces différentes dimensions de l'équité ne peuvent être ignorées sous peine d'échec. Elle permet ainsi d'identifier les voies selon lesquelles l'acceptabilité de la tarification de la circulation urbaine pourrait être améliorée.

Abstract

It is hoped that Automated Driving (AD) will make alternatives to the private car more attractive and facilitate the transition to sustainable transport. However, this expectation may underestimate both the resistance of private automobility and the unintended consequences of automated driving. Whether AD will contribute to sustainable mobility depends largely on its implementation and how its risks are prevented. This paper provides empirical insights into the design of acceptable forms of AD by investigating specific use cases with respect to the requirements of different mobility configurations. We pay special attention to people who travel with children. Our use cases comprise three probable types, covering the spectrum from demand-responsive transport (DRT) to private vehicles. Our results include the identification of mobility configurations and an analysis of AD use cases considering several empirically derived criteria: improved accessibility, ease of daily life and well-being, and improvement of the traffic situation and the transport system. Our analysis is based on a qualitative study in the Berlin area, Germany. The discussion focuses on the usefulness of AD against the background of different user perspectives, sustainability, and societal requirements, as well as an evaluation of AD in terms of its acceptability. We conclude that automated mobility use cases should meet the requirements of different mobility configurations to promote the transformation from private to shared automobility and, eventually, less automobility overall.
